Um, no.

My RPM libraries were in perfect running condition.  I could install,
remove, query, etc all my RPMS. Even remove them!
I had tried many times to overwrite my existing RPM libs, but RPM
won't overwrite them. So, I copied it from another
Centos 4.2 box, and tried it - nothing. Same thing.

The problem was selinux.  Once I installed Centos' version of SELinux,
and a few of it's dependencies, Yum worked.
I've gotten so far as to get it to almost upgrade to centos.  It balks
at hal and udev, since FC3 doesn't appear
to have udev. I'm tempted to remove the dev package and try let yum do
it's upgrade, but I don't want to crash the box.
After taking a look at the packages and such installed, I can see why
it is unsupported.  But, I'll give it a try.
If you want, I'll let you know how this frankenstein upgrade goes.
